An insulated electric wire and a method of producing the electric wire are provided. The insulated electric wire includes: a copper wire; and an insulating coating formed on a surface of the copper wire by an electrodeposition method. A cross section shape of the insulated electric wire including the insulating coating is in a hexagonal shape, a chamfered part that suppresses swelling of the insulating coating is formed on each corner part of a hexagonal cross section of the copper wire, a length of the chamfered part is &#x2153; to 1/20 of a length of a flat part of the hexagonal cross section, and a void ratio in a wound state is 5% or less.

Insulated electric wire and method for manufacturing same

Apparatus for assembling a grommet and a wire ring for forming a peripheral reinforcement of an engine head gasket opening. Grommets and wire rings are supplied one by one on different supply devices and retained at first and second article retaining positions, respectively. A movable head moves toward the second retaining position and picks up a wire ring. The head then conveys the wire ring to the second retaining position, where the wire ring is placed overlappingly on the grommet. Thereafter, another movable head having a deforming die is moved against the overlapped grommet and wire ring and deforms a flange of the grommet radially outwardly, whereby the grommet prevents separation of the wire ring therefrom. The thus assembled grommet and wire ring are conveyed to a machine for attaching them to the gasket.
